pub struct PyNone(/* private fields */);Expand description
Represents the Python None object.
Values of this type are accessed via PyO3’s smart pointers, e.g. as
Py<PyNone> or Bound<'py, PyNone>.

👎Deprecated since 0.27.0: Use ::classinfo_object() instead and format the type name at runtime. Note that using built-in cast features is often better than manual PyTypeCheck usage.
Name of self. This is used in error messages, for example.
